Thanks for your thoughts Ace. The tech at the time replaced all three parts. He was here for a few hours, the first replacement pump leaked. He ended up going back to dealership twice for parts. I asked him to leave me the old parts (possibly to test later). He had left the old pump at the dealer, but left board and heater. He seemed concerned and competent, but the 3 component failure within one week of my last use (we have had a heat wave), just doesn't seem right. I'm out $1,359, and reticent to unplug and test anything and possibly void the 1 year warranty on the new equipment if something fails.
